Unroot Help!

Folks,
I just received a note from my corporate email that my phone has been identified as a rooted device. I used Razrs Edge to root. However all the instructions that I have found to unroot also seem to erase phone. I am just looking for a way to unroot only. I want to make one last TiBu and then unroot no erase.
What are the options?

How could they find out your rooted? I've only come across this once before and that was when I was trying watch a movie in Google Play. It wouldn't let me because it had detected I was rooted. ( i always figured it was the superuser app that gave it away).

Whether you like, agree with it or not, IT sees rooting as a risk that potentially puts corporate data at a greater potential for theft, leakage, etc. there are several companies that provide tools for the corporate it department to do root detection. Of course there are also tools that try to bypass root detection, continuing the cat and mouse chase.
